Hi, I need to visualize points in 3D, whose positions are Gauss distributed. The expected values and the standard deviations for each x, y and z coordinate are given. So, how can I do that with OSG? I could draw a sphere (using osg::SphereDrawable) with a fixed radius at the center and another transparent sphere around it for visualizing the standard deviation. But that doesn't look nice... What I'm looking for is some kind of 3D-radial gradient. The transparency should increase along the gradient accourding to the Gaussian distribution function. Note, that the standard deviation can be different for each dimension. I'm a newbie in OSG and not an OpenGL expert. Some example code would be really helpful. Thank you
